Whiteabbey (Irish: An Mhainistir Fhionn[1]) is a townland (of 406 acres) in Newtownabbey, north of Belfast in County Antrim, Northern Ireland.

[3] In the first half of the 19th century, the village of Whiteabbey was home to a large bleach works, and was an important landing site for coal shipments bound for Belfast.

The importance of Whiteabbey declined after the channel into Belfast Harbour was widened and straightened, allowing larger ships to reach the city directly.

Abbeylands, a Victorian house in Whiteabbey belonging to Sir Hugh McCalmont, was used as a training ground by the Ulster Volunteers during the Home Rule Crisis.

[6] Whiteabbey, together with Whitewell, Whitehouse, Jordanstown, Monkstown, Carnmoney, and Glengormley, were the seven villages that formed Newtownabbey when it gained district council status on 1 April 1958.
